Szymekk ransomware is the threat that derives from the CobraLocker ransomware family. It’s a cryptovirus that, upon successful infection, encrypts users’ computer data, except non-system files, and demands for a ransom to receive a private decoding tool/key. After successful encryption of computer data, most ransomware places ransom notes as .txt files on the desktop and affected folders. Shymekk virus operates differently – it locks the computer screen and shows the ransom message in it. The message itself is very short. Cybercriminals just inform the victim that their device is encrypted and provide an email address (Cobra_Locker@protonmail.com), urging the users to contact them to receive further details.
